I have to convert 13000 all atom pdb files into files with c-alpha only. Is there any way i can convert all the files in one go using pymol??... Though i can convert each and every file but it will be quite tedious. |

Do I understand it correctly that you only want to retain the CA atom information from your original PDB file? In that case I would simply use some Linux shell scripting to select only the CA entries in the original PDB file. For one PDB file that would work like: grep ATOM "pdbfile" | grep CA that will give you the output on the screen; you can redirect this to a new file by doing: grep ATOM "pdbfile" | grep CA > "filename" If that gives the result you want, you simply have to loop over all your 13000 files and that's it... I think that is an easier solution than using PyMol, but I am sure you can do it in there as well (probably somehow via the Python shell scripting). Is there a specific reason you want to use PyMol for this purpose? |
